My invention relates to coil making apparatus and more particularly to an apparatus for making coils of rope, and other material, needed for ready use in logging camps, ship yards, and in all other places where such coils are used. The primary objects of the invention are to provide an apparatus or machine by means of which coils may be mechanically turned out and furnished for use in quantities at a large saving in time, labor and money. Further objects are to provide means whereby the coils may each be quickly formed, tied as a compact unit, and readily removed from the apparatus.

In the drawing:

Figure 1 is a view in perspective of the apparatus; and

Fig. 2 is a view in side elevation of the same showing the front detachable disc plate and a completed coil of rope removed from the drum.

Referring in detail to the drawing wherein like reference numerals indicate like parts in the several views, the numeral 5 designates the base plate of the apparatus which is provided with two spaced apart upstanding plates 6 and I that are respectively fixed to the base plate in any desired manner. Aligned bearings 8 and 9 are respectively fixed into the upper portions of the upstanding plates 6 and I and a horizontal shaft I is journaled through said bearings. A sprocket wheel II is keyed or otherwise fixed to said shaft between the upstanding plates. As shown in Fig. 1 of the drawing, a sprocket chain I2 is connected to the sprocket wheel and may lead to an engine, motor or other source of power, not shown, for the purpose of rotating the shaft Ill. Or said shaft may be manually rotated by a crank handle I3 installed on its rear end as shown in dotted lines in Fig. 2.

The forward portion of the shaft Ill extends at some length forward of the upstanding plate 'I and a hollow drum I4 is fixed thereon in any desired manner. The enlarged rear end of said drum is fixed to an enlarged rear disc I5. Said drum tapers or,converges to a considerable extent from the disc to its forward end it. Longitudinal openings N, that are preferably four in number and equally spaced apart, extend through the shell of the drum I4. The enlarged disc I5 is provided with four radial openings, as designated by the numeral I8, which register with the openings I! of the drum, and it is important to note that said radial openings extend both inside and outside the shell of the drum I4.

The forward end I6 of the drum I4 is provided with a shoulder I9, and a plurality of spaced apart pin lugs 20 extend forward from said shoulder and are provided with holes in their outer ends. A large forward disc plate 2I, that is equal in diameter with the disc plate I5, is pro- 5 vided with an annular opening 22 which is sufiicient in diameter to receive the forward end I6 of the drum and whereby the shoulder I9 thereof fits snugly against said forward disc in its installed position as shown in Fig. 1, with the pin 10 lugs 20 projecting through semi-annular cuts in the edge of the disc at the opening 22. Cotter pins 23, with small washers interposed, may be inserted into the holes through the pin lugs for retaining the detachable disc plate 2I in place, or any other desired means may be used for this purpose. Four radial openings 24 are provided through the disc plate 2 I, which openings register with the longitudinal openings I! of the drum I l and are aligned with the openings I8 through the rear disc I5. These radial openings are equal to the openings I8 in all respects except that they extend partly into the forward end I6 of the drum I4 and this is made necessary for the important purpwe of extending them inside the shell of the 25 drum It as well as outside thereof.

The forward detachable disc plate 2I has a hook 25 and several pins 26 connected to its outer face. In the use of the apparatus, the rope 21, which is to be converted into coils, is usually 0 passed from the inside through one of the openings 24 in said disc plate, then around against the pins 26, and a loop 28 which is tied in its end is caught around the hook 25. The drum I4 is then rotated until a coil of the desired size is formed thereon. The rope is then cut off and its cut end portion is passed around one part of the coil and tied, as shown at 29 in Fig. 2. The end portion having the loop 28 is now disengaged and passed through the opening 24 and then around another part of the coil where it is made fast as shown at 30. In passing the ends of the rope around the coil and making them fast thereto, it is obvious that same could not be done without the longitudinal drum openings I! together with the radial disc openings I8 and 24. These tying operations are made easy by means of the said openings. Although the drum be almost completely filled with rope, its ends may be readily passed around the coil and tied for the purpose of retaining same as one compact unit. After the coil is securely tied, the cotter pins 23 are removed, and the disc plate 2| is detached as shown in Fig. 2. The completed coil, as shown tan a a,

through'its shell, a large disc plate fixed to the inner and larger end of the drum, said disc plate having openings registering with the ends of the longitudinal openings in the drum and extendin both inside and outside of said drum, a large disc plate detachabiy connected to the outer and smaller end of the drum, said large detachable disc plate having openings registering with the openings in the drum and extending both inside and outside of said drum. 7 i
